Application filed April 27, 1912. Serial No. 693,712.

Toa l l it may concern:

that I, WILLIAM A. Soon, a tize or the United States, residing at i'ili' il unty of King and State of ashington, have invented certain new and useful'Improvements in Tnrbine-Engines; andI do hereby declare the following to be a .full, clear, andexact descriptionIof the invention, such as will enable others skilled in the art to which. it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters,

and figures. of referencef'markedthereon, which form apart ofthis specification.

'This invention relates'to new and useful improvements/in turbine engines, designed so W for use as motive power under force impart ed to the rotor by impact, adhesion, VlSCOSllZY' and static expansion derived from fluid,

such'as gas, ether, steamflor water,.the object in View being to provide an engine whereby the highest possible economy may be obtained ata minimum of energy.

The present invention comprises essentiallyan engine provided with rotor blades or plates having circumferential teeth adapted to receive the direct impact of the fluid as well as the faces of the disk receiving the impactof the fluid, thereby resulting in a higher starting torque and increased power at all speeds. f The inventiontcomprises various details of construction and -combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure 1 is a vertical central sectional view through my improved turbine, andv Fig. 2 is a section at right angles to the plane shown in Fig. 1. Y

1 Reference now being had to the details of the drawings by letter, A de signates the casing in which a shaft B is journaled in suitable ball-bearings F which are held against the races F by the threaded bearing plugs I, a suitable packing J beinginterposed between the race F and a shoulder formed at the inner end of the recess in which the race and bearingzplug are mounted. A gland I- is circumferentially threaded and fitted within the bearing member I.

Fixed 'to the shaft by means of spider spaced-apart a suitable distance by means of washers E or other means, and the circu'm ference of each disk is provided with a series of serrations or teeth'N adapted to receive the impact of fluid introduced through the inlet 0. Said casing is provided with a chamber K at each end of the series of disks and exhaust ports T lead from the opposite ends of the chamber through which the fluid may make exit.

In operation, the fluid being introduced through the inlet port 0 will be directed against the serrations about the circumferences of the disks, thus imparting, a propulsive force thereto and the impact of the fluid arms C is a series of disks D, which are against the faces of the disks taking a spiral course, the length of the spiral corresponding to the speed of rotation of the plates. By reason of the direct impact upon the disks together with the adhesion of the fluid to the disks, a high starting torque will result and a corresponding increase of power will be obtained at differentspeeds.

What I claim to be new is 1. A turbine engine comprising a casing having inlet and exhaust ports, a shaft journaled in said casing, a series of ,disks fitted to said shaft and spaced apart, the circuniference of each disk being serrated, as set forth.

2. A turbine engine comprising a casing having inlet and exhaust ports, a shaft journaled in said casing,- a series of disks fixed to said shaft and spaced apart, each disk mounted upon spider arms, the circumference of the disks being serrated, the spaces between the disks communicating with one another and with said exhaust ports, as set forth.

3. A turbine engine comprlsing a casing Q mamas 'having inlet and exhaust ports, a shaft jonrdisks and with the exhau naledin suitable bearings in said casing, forth. disks fitted to said shaft and spaced apart In testimony whereof I hereunto afiix my adapted to rotate in an enlarged portionqf signature in the presenceof two witnesses.
